I made one of the biggest mistakes of my life the night I went to watch Chelsea win the 2012 Champions League final.

You all know what happened. Chelsea were outplayed by Bayern Munich — as they had been by Barcelona and by Napoli in previous rounds — but they won the trophy.

It meant Spurs hadn’t qualified for the following season’s Champions League, despite finishing fourth — two points above Chelsea in the Premier League. They took our place as holders. I was distraught. I felt like crying.

Jamie invited me over — he said Sky had a box at the game and I should go as his guest.

Ruud Gullit was there and was carrying on right in front of me like a lunatic. He had nothing riding on the game — Chelsea had sacked him, for heaven’s sake — but he didn’t care.

Ruud was jumping around, cheering, singing, banging on the windows to draw the attention of the Chelsea players — and, when they looked up, in the background was me, feeling probably at my lowest as a football manager.

In the end, I think Jamie got quite upset on my behalf.

‘Ruud, do us a favour, they sacked you, didn’t they?’ he said to him. ‘Ah, yes, but that was different people,’ said Ruud and then carried on oblivious.

I felt embarrassed, really, as if I was spoiling the party, but I still think his behaviour was over the top.
